Question: Black screens and max fan speed
Question: Black screens and max fan speed
Hello everyone
I've been having an issue with my pc intermittently for the past year. Every now and then I get black screen and max fans and the only way to get display back is to restart my pc.
Build is :
CPU: Intel® Core™ i9-13900KF - 24-Core [8P @ 3.00GHz-5.80GHz / 16E @ 2.20GHz-4.30GHz] - 32MB Cache, Ultimate OC Compatible
M2SSD: 2TB WD Black SN850X M.2 NVMe PCIe SSD - 7300MB/s Read & 6600MB/s Write (Single Drive)
MEMORY: 16GB (2x8GB) DDR4/3200MHz Corsair Vengeance LPX Memory
MOTHERBOARD: MSI PRO Z790-P WIFI
VIDEO: GeForce® RTX 4070 Ti
POWERSUPPLY: Corsair RM850X 850W
After crashes and viewing event viewer I get the error for device raidport 1
I have 2 monitors, 1 being a new one I got with the pc a year ago and a second one which is a few years older
This crash happens at random intervals and can happen multiple times over and over and then not happen for weeks to months. Or can happen once every 2 to 4 days. There is only one situation in which I'm able to mimic this crash and that is when the pc is turned on I unplug one of the displays from the GPU and then plug it back in where it immediately black screens and max fans.
I have tried the following as per other people with similar issues:
sfc /scannow
chkdsk /scan
Changing power supply settings to GPU
Bios is up to date
All drivers are up to date
Repeating GPU seems to help it for an extended period of time but then the issue returns
Anyone got any advice
Thanks 😊
Usually this involves power aspects in some way. The initial action should be disconnecting and then reattaching all power cables. I'm thinking an adapter is being used for the 12VHPWR connector. If that's true, aim to connect as many individual PCIe 8-pin ports as possible (rather than linking them together), since it depends on the cables included with the PSU.
If It is a power issue and I was to use a 3x8 pin as opposed to the 2x8 pin would there be any bad side effects. I'm assuming the PSU won't force more than than the GPU pulls or am I getting my wires crossed?
I asked because I've seen some posts saying it's a better alternative and others saying there isn't a difference. I would have thought that using a 3x8 would just allow the GPU to be able to draw more power when it requires.
In my view, you should stick to the adapter that came with your specific card. For instance, my 3080 comes out at 400W even though the NV standard is 320W, which means it has three 8-pin connectors instead of two. With the 4070 Ti, it's a 285W card where each 8-pin supports 150W and the PCIe slot allows up to 75W, so unless your card is exceeding 285W, an adapter with two 8-pin connectors should work. I recommend using two separate cables from the PSU to connect it.
Soooo I've taken these steps...
Purchased a new 12VHPWR 2x8 pin and replaced them. The same problem happened again—like unplugging the monitor and plugging it back in caused a black screen with maximum fans spinning. This is the only way I’ve managed to recreate the issue on demand. Then I bought a 3x8 pin, and after careful but gentle unplugging so far, there are no problems. I’m still unsure because it seems like it was fixed before, but then it crashes again, just like my father did with the milk.
If this fixes the problem, my next question is... what’s most likely causing it? Could it be the cable, or should I worry about the PSU sockets? Maybe even the GPU has a fault. I’m not very experienced with the mechanical side of PCs, so I’m just worried there might be another hidden issue.
